Hey, thanks for reporting the bug! I have a couple of things I'd like to ask. First, What do you mean by towards the middle? Also, Which scene and mood was it? The normal scene, or the penalty scene? At what timing did you use the item? during a running dialogue, or no? And lastly, how many of those items did you use at once?
I'm sorry if I'm asking too many questions at once but it'd help me locate the bug faster if you can provide me with a few more details. Again, I appreciate the feedback and I'm sorry for the inconvenience.
